Key ratings and what they mean for your fit
The 68020-144HLF: The 44-position count across two rows supports high-density signal or low-current power runs on a single connector. The 3 A per-contact rating is governed by the phosphor bronze contact material and the 30.0 µin gold plating — the gold grade here drives the current ceiling compared to tin-plated variants. The 0.190 inch (4.83 mm) insulation height and 0.095 inch (2.41 mm) post tail length set the board-stack geometry: the header sits low-profile on the daughtercard, and the post must fully pass through the PCB land to achieve a reliable solder fillet in wave or hand-solder assembly. Contact length at mating is 0.230 inch (5.84 mm), which sets the engagement depth with the receptacle — critical to confirm the mating half's pin length meets or exceeds this to avoid stubbing on insertion.
Sourcing and lifecycle
The 68020-144HLF carries an Active product status on record. It is sourced to BOM quantity against an RFQ; no official successor or cross-reference is listed in this series. Confirm position count and mating half before committing — the 44-position count and right-angle orientation are the two fields most likely to collide with a similar-looking lower-position variant on the same series footprint.
